CANON 10D

[steveb121]

CANON 10D 3 years old, only canon lenses, has started displaying 'error 99' nearly every other shot. Have tried on/off and reinserting the battery as per the manual. Seems to be getting worse. Any ideas besides a new camera?

[forrest64]

How about sending it to a Canon repair facility?

[steveb121]

Thanks Forest64, it may have to come to that unless there is an easy solution

Yes you played with the BP511 battery, but I guess not the CR2025 (button shape) battery underneath. It may be responsible for basic instruction set; cpu clock etc. They age. This is a 'new' problem for 10D - perhaps- but it would have to have been a similar problem on the older D60 & D30 - so do a search... page 155 in the manual..

Have you tried a different BP511 battery ? How old is the battery you are presently using ? I'm wondering if the battery voltage may indicate a good charge, but when under load of focusing the lens, internal camera processing, and taking the picture it incurs a voltage drop (internal resistance of the battery increasing with age) which results in an error 99. Possibly try cleaning the battery contacts as well.

Err99 can also be caused by poor connection between the camera and lens. Make sure that you have cleaned these properly before sending in for repair.

Err99 is a catch-all. Could be the camera-lens contacts, a lens problem, a shutter problem, . . . Not a lot of help, am I? Does this happen with more than one lens? Try cleaning the lens contacts with an eraser (keeping the crumbs out of the mirror box). Does the shutter appear to be working properly? Is this happening on the second picture of a 2 or more picture burst, or is it just every other picture regardless?

[steveb121]

Thanks Guys for all your suggestions. My observation that the fault being every other shot may be a red herring. It does show up the fault on every creative setting including picture burst. I have about 7 bp511's of varying manufacture including the original Canon one all the others less than 1 year old, so I don't think it's a battery problem. The problem exists with all lenses, 2 Canon and 1 Sigma, (brand new). I will try cleaning the lens contacts and will order a new cpu battery underneath. I did notice however that the time on the camera was about 7 minutes slow! Is this a clue? The camera is just in its 4th year now

I would say the lens...............However, contact Canon about the problem.

Any idea how many clicks on the shutter you are at?

[steveb121]

Hi bauerman, I have over 10,000 shutter clicks. Is this where my problem is?

[Jon]

10,000 clicks seems a little low for the shutter to be failing (a possible Err99 cause). The MTBF is reportedly about 50,000, so this would be way on the low side. I wouldn't worry about the system time being slow unless you reset it when you transitioned to Daylight Savings Time (in which case, it's really losing fast). Even if you had, that wouldn't normally cause an error. You say it happens in "every creative setting". Does this mean that it doesn't show up in the Basic modes, or merely that you don't use them?

If a new back-up battery and cleaning lens and battery contacts don't fix it, though, you may need to send it in for repair.

I probably should not be offering advice on the first post. But I would try another CF Card just to make sure it in not a write error that you are getting. CF Card error for me was Err02 but it seems like you have tried everything else.... Good Luck.......... because I know there is nothing worse than one of your "babies" being sick.

I figure a first post needs a first pic.........it got distorted when I saved as jpeg....but ... its a fun pic.

Edited: Well the pick is too big and I can't get it small enough to get on this site: Proof that I should not be offering advice :(

Welcome to a new poster, regardless of how you look in your pic.

I had the same problem with my 10D. I tried batteries, lens contacts, different CF cards all to no avail. I was sure the lenses were okay because my 20D worked fine with the same lenses, batteries, and cards. I then removed the battery and the button cell. I turned on the camera switches and left them in that state overnight. The next day I reinstalled the same batteries, cards and lenses. I have since shot over 100 shots with no problems. Give it a try, it might work for you also.

Err99 can also be caused by poor connection between the camera and lens. Make sure that you have cleaned these properly before sending in for repair.
This is what I was going to say, but Sheldon beat me to it.

I've had my 10D for two years. Tonight I got the Err99 for the first time. I removed the lens and battery briefly and the camera worked fine. It sounds like this is going to be a trend.

Internal clock being slow may indicate that the button cell is dying, I would replace it. I had an IBM laptop that displayed a 192 error and the clock kept losing time. It it turned out to be the CMOS battery, the button cell does the same thing in the 10D. I would get a new one. They are only a couple of bucks. GOOD LUCK!

I usually clean electrical contacts with 96% ethanol... or stolichnaya :rolleyes:

No crumbs in the mirror box that way.

[steveb121]

Thank you all for your suggestions as to my error99 problem, alas, all to no avail. I am now waiting for a new Cmos battery as a last resort before I wave my beloved goodbye to the great Canon service department in the sky, never knowing when I will see her again. Please guys, don't make me send her away...please...

Interesting suggestion AntoineL

steveb121,

I'm sure you would do this anyway, but will you please post an update for all us 10D owners letting us now what the error 99 problem was, once fixed.

THANKS

[steveb121]

Of course MAD DOG . Guess what? I took over 100 shots yesterday & today with different lenses and NO Error99. It WILL come back though, guaranteed.
